HEEL-BREASTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 636,990, dated November 14., 1899.

Application filed March 80, 1898- To all whom it may concern.-

Be it known that I,JOHN J.HEYS,of Lynn in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Heel-Breasting Machines, of which the following is a specification.

This invention has relation to machines for cutting away the heels of boots and shoes, but has relation more particularly to machines for breasting or cutting away thebreasts of the heels; and it consists of a machine possessing certain features of construction and relative arrangement of parts, all as illustrated upon the drawings and now to be described in detail and finally pointed out with particularity in the claims.

Reference is to be had to the accompanying drawings,and to the letters and figures marked thereon, forming a part of this specification, the same letters and figures designating the same parts or features, as the case may be, wherever they occur.

f the drawings, Figure 1 represents in plan View a machine embodying the invention. Fig. 2 represents a side elevation of the same. Fig. 3 represents a longitudinal section through the same with the knife withdrawn. Fig. 4 represents a similar longitudinal section, the parts being broken away, the knife in this case being at the end of its throw. Fig. 5 represents a transverse section on the line 5 5 of Fig. 2, looking in the direction of the arrow 00. Fig. 6 represents a section on the line 6 6 of Fig. 2, looking in the direction of the arrow y. Fig. 7 illustrates the gage with a shoe against it, so as to show the manner of centering the shoe. Fig. 8 represents the two-part gage which may be employed. Fig. 9 represents a plan view of the latter. Fig. 10 represents an enlarged transverse'section on the line 10 10 of Fig. 2.

tional view representing the same, the gage Serial No. 675,738. No model.)

being in this case omitted. Fig. 17 shows, in addition to the parts illustrated in Fig. 15, the mechanism for separating the gages for the heel. Fig. 18 represents a side elevation of the machine from the opposite side from that seen in Fig. 2. Fig. 19 represents in side elevation the rear end of another embodiment of the invention. Figs. 20 and 21 are sections on the lines 20 20 and 21 21 of Fig. 19.

Referring to the drawings,which show one form of machine which I have selected for the purpose of illustrating the invention, a indicatesa base-plate, which may be supported by legs or standards a. Bearingbrackets a rise from one end of the plate or bed, and shafts b b are jou rnaled therein, the former being the driving-shaft,to which power is initially applied, and the latter, I), being the shaft which imparts movement to the knife and which is driven at a relatively low rate of speed. Upon the shaft b is loosely secured a belt-wheel b, there being suitable clutching devices between the wheel and the shaft to connect the two together whenever desired. A pinion b on the shaft 1) intermeshes with and drives a large gear-wheel b on the shaft 12', there being on the last-mentioned shaft an eccentric c, and connected to the strap 0' is an eccentric-rod 0 by means of which the knife is reciprocated, as will be hereinafter described.

Upon the standard at, rising from the central part of the bed a, is a horizontal table or plate cl, having undercut flanges 01 as shown in Fig. 6, to receive a dovetailed carrier or slide 6. This carrier or slide is provided with a socket e as shown in Fig. 16, to receive the shank of the knife f. Ascrew f is threaded into the end of the shank and bears against the rear wall of the socket 6 so that by turning this screw the knife f may be adjusted in and out of the socket. After being once adjusted to the proper point the knife is held against movement by a screw 6 passed through an arch e of the slide and bearing against a wearing-block e placed upon the The rear end of the slide e is bifurcated to receive a link g, hinged thereto by a pintle g, extending through the slide,

as illustrated in Fig. 16, and the link g is in turn bifurcated and connected to the eccentric-rod c by a pintle g Thus far it will be seen that for each reciprocation of the eccentrio-rod the slide and knife will be likewise reciprocated.

Secured to one side of the table d is a grooved strip or plate It, slotted, as at h, to receive the screws 7L2, which hold it in place, but which permit it to slide back and forth relatively to the table. On its rear end the plate or strip is formed with an upwardlyprojecting portion h having a curved groove 7%, slightly offset at 7L5. (See Figs. 12 and 13.) The groove is on the inner side of the plate, and it receives a trundle or roll 9 on the end of the pintle 9 which, as stated, connects the eccentric-rod c with the link g. A spring i connects a pin 7L6, projecting down from the plate It, with a pin 1', projecting out from the bracket d, so that the trundle g normally remains in the oifset it in the slot 71 When the eccentric-rod is projected, the. eccentricrod and the link are in alinement or at a deadcenter, and they force the knife-slide and the strip 7t forward until the strip his prevented from moving farther or meets with a serious resistance, whereupon the continued move ment of the eccentric-rod causes the trundle g to engage the wall of the slot 77. at 77. and roll up the curved slot h and complete its full stroke, even though the knife-slide and the strip 7t remain stationary. The parts 0 and g constitute a toggle for operating the knife-carrier positively or unyieldingly, and said toggle is broken by the hunter at the moment the knife has completed its work upon the heel.

Upon the strip his mounted a fingerj,shaped as shown in Figs. 1 and 11 and having its free end very slightly in advance of the edge of the knife. The other end of the finger is pivoted atj to the end of the strip h, and the free end may be adjusted relatively to the knife-edge by a screw j passed through a bracketj secured to the side of the strip h, the end of said screw bearing against the finger, as shown in Fig. 17. The finger and the strip it constitute a hunter or mechanism for stopping the travel of the knife when it has cut through the leather of the heel to a proper extent and while the power devices complete their full throw, and they likewise perform the function of destroying the operative relation existing between the eccentric-rod and the knife-carrier.

The support for the sole of the shoe consists of a plate 7c, pivoted at k to an arm extending up from the bed or plate a, and in order to hold the supporting-plate 70 at any angle relative to the bed it is provided with a downwardly-projecting web 70 to which is pivoted a link is, the end of which is slotted and serrated, as shown in Figs. 1 and 2. A screw 70 is passed through the slot into the bed-plate, and its head presses a serrated washer 70 against the end of the link, so as to hold it against movement. By loosening the screw 70 the shoe-supporting plate may be adjusted about the pivot or fulcrum 70' to the angle desired. The upper converging end of the plate 70 is flanged, as at 70, to provide a support for the base 70 of a gage 70 for the toe of the shoe, by means of which the shoe may be properly positioned upon the plate.

Pivoted upon the front face of the plate are two positioning fingers or levers Z Z, having their lower ends shouldered and outwardly spreading, as at Z. They are provided with inwardly-projecting portions Z having teeth upon their ends which intermesh, whereby when one of the arms Z is swung about its center of motion the other arm is likewise moved and to the same extent. One of the arms Z swings loosely about its pivot-stud Z while the other arm is rigidly secured to its stud Z so that in case the latter be partially rotated or rocked the two arms will be both swung about their centers. The studs Z Z pass through slots k in the plate 70 and are set into a cross-bar m, which has a rib m lying in a slot 70 in the plate 70 and movable longitudinally of the said plate.

Upon the upper ends of the arms ZZare journaled rollers Z lying in a curved slot '21. in a guide likewise formed with a rib to project into the slot 70 from the front. (Shown in Fig. 3.) An adjusting-screw n is threaded into the guide and has its lower non-threaded end supported in astud 7c, projecting forward from the plate 70 and bridging the slot 70 as illustrated in Figs. 3 and 4. By rotating the screw n the guide-strip, together with the positioning-arms ZZ and the crossbar m, may be all adjusted longitudinally of the plate to change the position of the arms Z Z for shoes of different sizes or having heels of different sizes.

Usually after the heel has been placed upon a shoe in the process of manufacture a top lift is spanked in place, the top lift being usually smaller than the heel, the dimensions of which are subsequently reduced by proper tools to correspond with those of the top lift. Consequently when it is desired to breast the heel the shoe is positioned with relation to the top lift and not to the remainder of the heel. Hence the shoe is placed against the supporting-plate 70 with the corners of the heel fitting in the notches in the ends of the arms Z, and the toe of the shoe is held against the gage it so that the median lines of the shoe are parallel with the said gage, after which the knife is advanced to cutthe heel.

The shoe is jacked against the plate by the following devices: The bed-plate a is extended at a to receive a bracket a on the bifurcated end of which isjournaled ashaft 0. The

bracket is secured in place by a screws, passed through an enlarged aperture in the bed, and the bed and bracket are both serrated, so that the latter can be adjusted toward and from the shoe-support. A hand-wheel 0 is placed upon the end of the shaft, and between the bifurcated arms of the bracket a is placed aspiral cam 0 having its cam-rib 0 extending between a pin 0 secured to a sliding bar 0 and a roller 0 as shown in Fig. 3, this roller lying in asocketin the end of the slide-bar 0 To the opposite end of the slide-bar is pivoted a foot-piece 0 to bear against the top of the last and press the shoe against the supportingplate It. Thus it will be seen that by turning the hand-wheel 0' the slide-bar 0 may be forced forward or retracted as desired to clamp the shoe against the supporting-plate or else release it therefrom. When the shoe has been jacked in place by the jacking device just described, the knife is advanced; but inasmuch as the positioning-arms Z Z are then in the way of the knife I provide means for swinging them out of its path as it advances. These means consist of a bent arm 19, secured rigidly to the pivot-stud, and a cam-lever p, pivoted at p to the table. Upon the knife-slide is mounted a roller 19 which as the slide advances engages the bent portion of the leverp and swings the forward end outward. The bent arm 19 bears against a screw 19, passed through the forward end of the arm go, so that as the forward end of the latter is thrust outwardly the arm 19 is swung about its center of motion to rock the stud and cause the lower ends of the arrnsl Zto swing apart. The armsl Z are connected by a spring, which normally holds their lower ends together; but they are held apart by a screw q, passed through the arm p and bearing against the edge of the plate It, and by rotating the screw their ends maybe adjusted toward and from each other.

The operation of the machine is as follows:

The shoe is placed against the plate with the corners of the top lift fitting in' the notches in the arms Z and with the toe properly positioned with respect to the gage [68. Then the handwheel 0 is rotated to advance the slide-bar 0 to jack the shoe in place. Then by a suitable treadle mechanism (not shown) the clutch devices are thrown into operation to connect the belt-wheel b with the shaft b. Immediately thereupon through the medium of the gearing previously described a rotation is imparted to the shaft 1), and as the shaft begins to rotate the eccentric-rod is projected, forcing forward the knife-slide, which as it advances causes the positioning-arms to separate and move out of the path-of the knife. At this time the link and the eccentric-rod are in alinement and the knife continues its travel (the fingerj and knifefpassing through an aperture in plate Zc)i1ntil the fingerj strikes against the insole and stops the travel of the sliding strip h, whereupon the roll g engages the curved wall h of the slot h and travels up the slot 7%, while the knife and its carrier remain stationary. Then the knife slide or carrier is withdrawn, and when the shaft 1) b has completed one revolution by devices not shown the clutch devices are thrown out of engagement with the shaft and wheel and the shaft b is stopped.

I may employ any desired stopping device, such as a brake-shoe r, to engage a frictiondisk 1" on the shaft 1), the brake-shoe being connected to the sliding sleeve r which actuates the finger r through the medium of which the clutch devices are actuated to engage the belt-wheel b with the shaft 19.

Where broad-toed shoes are being breasted, I may employ a gage 70 as shown in Figs. 8 and 9, which may be placed upon the gage 70 and secured at anydesired height thereon. The device shown is provided with two fingers 70 70, by means of which the corners of the toe may be positioned.

It will be observed that the edge of the knife when viewed from the end is curved in the arc of a circle, and consequently it is desired that the ends of the arms Z should move through the same are, so that the shoulders on the ends of the arms may always remain in alinement with the knife-edge.

By reason of pivoting the arms L they naturally move in different paths, and consequently the upper ends of the arms are provided with rollers extending into the curved slot in the cross-guide 'n. This slot is either straight or so curved that when the arms are swung outwardly to accommodate a heel of any size the arms not only swing about their pivot-studs, but are also raised bodily, whereby they swing in an are or in a straight line parallel with the edge of the knife, which may be either curved or straight. This is an important feature of the invention, because if the ends of the arms do not swing in an are parallel to the arc of the knife a large heel would be presented to the knife in such way that more of it would be cut away than would bedesirable,whileasmall portion of a smaller heel would be removed, leaving the heels relatively unfinished.

Another important feature of the invention is the mechanism by means of which the knife is positively driven to cut away the heel and is automatically stopped before it has an opportunity to cut the sole, this mechanism operating perfectly with heels of different thicknesses.

Heretofore breasting-machines have been of either of two kindsthat is to say, the knife was positively driven a predetermined distance each stroke, and it was necessary to adjust the shoe-holder for each height of heel in order that the knife should cuttherefrom the proper amount of stock or else-the knife was connected with its driver by yielding means, as a spring, and a hunter was positively or rigidly connected to the knife to strike against the sole and arrest the motion of the knife after it had penetrated the heel to the desired extent. The present machine, however, is provided with means for positively--t'. e. unyieldinglydriving the knife, and also with mechanism for automatically arresting the motion of the knife when it has completed its cut through the heel and be fore it has a chance to cut the sole, and in this connection I desire to state that whenever I use the word positively in connection with the driving mechanism it will be understood that I mean thereby that the knife is driven unyieldingly.

As will be readily apparent to those skilled in the art to which this invention appertains, various changes in the construction and arrangement of the parts of the hereinabovedescribed machine may be made without departing from the spirit and scope of the invention, and the several features or parts may be utilized separately or in connection with machines of other constructions. For instance, in Figs. 19, 20, and 21 I have illustrated the rear end of a machine in which the throw or movement of the knife-carrier is always the same and the shoe is adjusted toward or from the knife. In this embodiment of the invention the knife-carrier is c011- structed substantially as hereinbefore described; but it is connected by a pivot to the reciprocating rod, so that its movements are always of the same length or degree. A carriage t is slidably mounted on the base-plate of the machine and is provided with a rigid block t, depending into a longitudinal slot 25 from which block a pin t projects downwardly and pivotally supports a block. (Shown in dotted lines in Fig. 20.) An arm to is pivoted upon a stud under the base-plate and is provided with an eccentric slot a, into which the block 15 extends, so that if the arm be swung to one side or the other the carriage will be moved toward or from the knife-carrier. To accomplish this movement of the arm u, it is connected by a link a with an arm u frictionally engaging a shaft of, journaled in the end standards of the machine, and another arm u rigidly secured to said shaft, havingits outer end connected by a link u with a treadle, (not shown,) by means of which the belt-wheel is clutched to the main driving-shaft of the machine. A spring (likewise not shown) normally holds the arm u in the position illustrated in Fig. 20, so that the carriage is withdrawn. Upon the carriage is mounted the sliding bar 0, the cam 0 and the hand-wheel o, the latter not being shown, and also the gage-plate, support, or abutment v forengaging the face of the heel and holding the heel in any desired plane relatively to the knife. The plate is pivoted by a pintle o in a lug 12 extending upward from the carriage, and it has a downwardly-projecting finger 11 to which is pi voted a connecting-rod 7;, having in its free end a slot 0 through which a bolt 11 passes into the carriage to adj ustablysecure it. By loosening the bolt o the gage-plate may be adjusted to any desired positiomsubstantially as hereinbefore set forth. In order to prevent the knife from cutting the sole when the shoe is jacked against the plate '0 in the carriage and the carriage is moved toward the knife, I employ a guard or bunter consisting of an arched rod to, spanning the carriage and pivoted in brackets w, secured upon the base-plate on either side of the carriage. This rod has a finger 10 through which an adjusting-screw 10 passes and bears against the base-plate, whereby the said bunter may be adjusted in lines substantially parallel with the lines of movement of the knife. In this embodiment of the invention the shoe is jacked in the carriage, and the latter is moved forward until the sole rests against the hunter. This is accomplished by the first movement of the treadle when it is depressed, the arm 10 being frictionally mounted upon the shaft 10 to permit a further rotation of the shaft caused by the further depression of the treadle to start the machine.

The bunter is automatically adjusted for the various heights of heels to be breasted, and in this way the cutting of the sole is prevented.

I have also contemplated the employment of a stationary knife and the use of a carriage to move the shoe against it, this being likewise included in the invention.

Having thus explained the nature of the invention and described a way of constructing and using the same, though without attempting to set forth all of the forms in which it may be made or all of the modes of its use, I declare that what I claim is- 1.
